Renowned Eurosceptic Andrew Bridgen claimed during an interview with BBC Radio 5
that he knows of at least 50 fellow Conservative MPs who are
already preparing to go for a vote of no-confidence in David
Cameron if the result on the 23 June is not decisive.

Dorries and Bridgen belong to a group of Conservative MPs who are
angered by claims that the prime minister has made while
campaigning for Britain to stay in the 28-nation bloc.

"There are many issues about which David Cameron has told
outright lies and the trust because of that has gone in both him
and George Osborne," Dorries told Peston.

William Hill's latest odds will make yet more worrying reading
for Leave campaigners as it's not just bookmakers but polling
analysts too, who are now saying that the chances of a Brexit
taking place are slim.

As seen below, analyst Matt Singh's most recent forecast said
that the probability of Britain voting to leave the EU was lower
than 20%.

The task that David Cameron faces in campaigning for Britain to
stay in the EU while preventing his party from descending into
all-out civil war is one of the greatest challenges of his
political career.

It is starting to look like that the outcome of the June 23
referendum won't just have profound consequences for Britain's
future but possibly the prime minister's too.

"There has been a sustained gamble on David Cameron being out of
office before the end of this year ever since he confirmed the
date of the EU Referendum," said William Hill's spokesman Graham
Sharpe in an email to Business Insider.

"Political punters seem to believe that even if the EU Referendum
produces a 'Remain' verdict, the Tory Party will have become so
destabilised that the clamour for a new leadership election will
become irresistible."
